ERNEST I. DARGIN, OF LOS ANGELES, CALIFORNIA, ASSIGNOR OF ONE-HALF T0CHARLES S. BROWN, 0F LOS ANGELES, CALIFORNIA.

FLUSHING APPARATUS FOR GARBAGE-CHUJJES.

To all whom it may concern:

Be it known that I, ERNEs'r P. DARGIN, a citizen of the United States,residing at Los Angeles, county of Los Angeles, and State of California,have invented certain new and useful Improvements in Flushing Apparatusfor Garbage-Chutes; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the charactersof reference marked thereon, which form a part of this specification.

My invention relates to improvements in garbage chutes of the characteremployed in hotels, apartment houses, etc., and of the constructionwhich extends the entire height of the building and which has openingsat each floor for the introduction of garbage. My present inventionrelates specifically to the means for automatically supplying water tothese chutes for flushing purposes, whenever a door is opened for theintroduction of garbage. This invention discloses in its generalcharacteristics those disclosed in. my simultaneously pendingapplication entitled Improvements in sanitary garbage chutes, but theclaims will be drawn to cover the flushing construction alone.

An important feature of my present constructionconsists in the locationof the water pipe or conduit from which the supply is taken at eachfloor, within a closed chamber or compartment adjacent the body of thechute and in communication therewith, whereby in case of a leaky valve,the escaping water will drain into the chute and therefore can do nodamage to the building. Heretofore, so far as I am aware, chutes of thischaracter have had the valves for controlling the supply of water to thechute,

struction and arrangementof the door of v the chute at each fioor,whereby as the door is'opened, the water is automatically turned on,while when the door 1S closed, it is turned,

Specification of Letters Patent.

Application filed March 8, 1915. Serial No. 13,067.

ofi. In the drawings, I have illustrated. both a sliding and a hingeddoor for accomplishing this object.

Having briefly outlined my improvement, I will proceed to describe thesame in detail, reference being made to the accompanying drawing, inwhich is illustrated an embodiment thereof. In this drawing,-

Figure 1 is an elevation of a garbage chute of my improved construction,the same being illustrated in use, enough of the chute being disclosedto permit the explanation of its use on any floor of a building,regardless of the number of floors.

Fig. 2 is a fragmentary elevation of the construction, partly insection, the view being taken in the direction of arrow 2, Fig. 1, theparts being shown on a larger scale.

Fig. 3 is a similar view shown entirely in elevation.

Fig. 4 is a vertical section taken on the line 45, Fig. 3, lookingtoward the right, and showing the door in the open position.

Fig. 5 is a similar view showing the door in the closed position.

Fig. 6 is a view similar to Fig. 4:, but showing another form of doorconstruction. In this view, the door is shown open.

Fig. 7 is a view similar to Fig. 6, but showing the door closed.

The same reference characters indicate the same parts in all the views.

Referring first to Figs. 1 to 5, inclusive,

let the numeral 5 designate the body of the chute, 6 its upper extremityextending above the roof of the building, and open for ventilatingpurposes; 7 the garbage receptacle at the bottom of the chute; 8 avertically movable hood arranged above the receptacle for closingpurposes; 9 a lever for raising and lowering the said hood; and 10 afloor of the building where the chute is located, the same being shownin section.

At a suitable distance above each. floor 10, the chute is provided withan opening which is normally closed by a door 12, which, as illustratedin the views now under consideration, is vertically movable in thegrooves 13 of channel guides 14 and 15 with which the chute is equipped.The lower members 14 of these guides are built into the housingstructure 16 applied to the chute adjacent each opening, while the uppermembers 15 of these guides are fastened, as by means f ri et it to th uper region of the housing structure 16 and extend above the same, beingcompletely exposed or separated from the body ofthe chute, and areadapted to receive the opposite edges of the door when the latteris-lifted. The upper extremities of the guide members 15 are con;

- spaced at the top and b'ottomby transverse parts 22 and 23. Thisspacing of-theplates 20 and 21 forms a chamber 24: within the door, intowhich protrudes a crank arm25, whose outer extremity passes through anopeningv 26- formed in the inner wall of a housing27 and whose outerwall 28 is exteriorly cl0sed. Located withinthis housing isa branch pipe29 which passes through'an opening 30 formed-at the top ofthe housing 27and is connected within the main water supply conduit--31 by means ofa-conduit member 32.

. of: the door, the, spring 39 is stretched or.

Within the chamber 33 of this housing, the branch-pipe 29 isequipped-with-a valve 34:, for controlling the supply of water'to thechute as the dooris opened. The outer extremity of "the crankvarm 25 isconnected with. this valve, the arrangement being such that when thedoor is closed or in the position shown in Figs..2,f3-:and '5, the valveis closed and the watercutoftfrom the chute.

This crank arm, when the door is closed,

is downwardly inclined from the valve at.

an angle of approximately 45 degrees and is provided with a slot 35which is entered by a pin '36 fast uponthe door. Connected with thiscrank arm at a suitable-point between its extremities, is one end of aspiral spring 39, whose upperextremityis connected with the-part 22 atthe top of the'door, as shown at 37.

"Gonsequently, as the dooris raised, the crank arm 25 is carriedupwardly therewith and imparts suflicient movement to the valve 34 toopen the-same. The position of the crank-arm when the door has reachedits upwardlimit of movement is indicated by dottedlines in Fig. In other'words,when the crank arm .2 5 has-rea ched this position, the doorcannot be raisedfarther, since the pin 36 engagingthe slotj35 of thecrank arm will not permrt further movement. 5 During this upwardmovement placed under tension, since the point "37 where theupperextremity ofthe spring '39 is connected with the door, must travel.far-

- ther than the point 38' wher'e -this same 1 spring-is connected with.the'crank arm. In other words, the point 37 must travel the fulldistance between the full line position of the pin 36 in Fig. 2 and thedotted line position of thesaid pin in the same figure, while thepoint'38 can only travel the distance betweenthe full line position ofthis point in Fig. 2 and the dotted line position of the same point inthe same figure, hence the spring 39 will be distended and its recoilaction will aid in returning the door to its closed position, and alsoperform the function of closing the valve 34..

The outer wall of the housing 27 is downwardly inclined at its lowerextremity, as shown at 40, whereby any water which leaks into thechamber-33 of this housing will pass downwardly into the chute throughan opening 4 1 'formed .in the inner wall of the housing, andcommunicating with the interior of the chute.

In the form of construction shown in Figs. 6 and 7, a door 42 ishingedto a housing 43,-whichis offset from the body of the chute. Withinthis housing is located a branchpipe or conduit 44 in which a valve 45is located. Connected with this valve is a crank arm 46 with which oneextremity of a rod 48 is pivotally connected, as shown at 47,-theopposite extremity of the said rod being pivotally connected as shown at49, with an inwardly projecting crank arm 50, which is secured-to thelower extremity of the door, and is raised by the opening movement ofthe door, as illustrated in Fig-6. The door is normall y held in theclosed position bymeans of a weight 51 which is connected withthc innerextremity of the crank arm 50 this weight also has the function ofaiding, in closing the door.

The housing structure in which the pipe 44, its valve and the meansconnected with. the door for operating the valve, are located, isofi'set from the body'5 of the chute in such a manner as'to be out ofthe path of the garbage passing thcrethrough from the floors above anydoor and its connections. The lower extremity-of the branch water supplypipe 44 extends transversely of the chute and parallel with the loweredge of the door, as shown at 52 inboth forms of constructions, thispipe member being perforated for the escape of water into the chute forflushing purposes. In the form of construction shown in Figs. '6 and 7,a defiectingplate 53 extends inwardly from the outer wall of the housingbelow the-door and above the transverse perforated member 52 of thewatersupply pipe, and prevents anywater from escaping into the apartment whenthe door is open.

From the foregoing description, the use and operation of myimprovedflushing ati tachment for garbage chutes will be readily understood.In'the form-shown in-Figs. 1 t0;;5, inclusive, the door which isprovided with a handle 54;for thepurpose, is raised till for openingpurposes, whereby it is carried upwardly so that its opposite verticaledges engage the channel members 15. The door is shown in this positionin Fig. 4, the spring 39 being distended as illustrated in this view.The opening movement of the door actuates the crank arm 25, with whichthe said spring is connected, sufiiciently to open the valve 34, wherebywater is allowed to enter the chute for flushing purposes.

In the form of construction shown in Fi s. 6 and 7, the door is swungoutwardly tor opening purposes (see Fig. 6), and during this movement,the inner extremity of the crank arm 50 is moved upwardly sufiicien'tlyto actuate the valve 45 for opening purposes, through the medium of thecrank arm 46 and connecting rod 48. The act of closing either form ofdoor, reverses the movement of the valve piece and cuts 0d the water sothat there shall be no escape of the water when the door is open.

Having thus described my invention, what I claim is,
